Helmet with pivotable visor
US 4312078 A
A motor cyclist's helmet has a visor apertured at either side so that it can pivot on pivots projecting from the helmet. At one side, the aperture in the visor is elongate so that this side of the visor can be pushed forward, the visor being slightly deformed outwardly. A pin projecting from the helmet and received in a slot in the visor then permits the visor to be pivoted upwardly, which the pin and slot prevents when the visor is pushed back against the helmet. The visor can be operated by one hand, with the help of a projecting portion of the visor or a gripping member affixed thereto.

The invention relates to a helmet mounting a visor, for example a protective helmet of the kind worn by motorcyclists.

Motorcyclists' safety helmets, particularly those of the full face type, are provided with a visor which is movable between a closed position covering the eye aperture of the helmet and an open position in which the aperture is exposed. Movement of the visor between these positions frequently presents considerable manipulative difficulties. For example, it is in many instances necessary to release one or more press studs and, after pivotation and realignment, to refasten them. The visor frequently has to be manipulated at both sides so that either both hands must be used, which represents a considerable inconvenience because of the need for a motorcyclist to keep one hand on the throttle, or one hand must be used to operate on the two sides of the visor in sequence.

It is thus an object of the invention to provide arrangements for mounting a visor on a helmet which provide for simple and convenient operation of the visor.

It is a further object of the present invention to provide visor mounting arrangements on a helmet which permit movement between visor open and visor closed positions by operation at one side only.

It is an additional object of the invention to provide visor mounting arrangements on a helmet which permit the visor to be opened and closed by manipulation at one side only and which permit this side to be conveniently changed.


The invention provides a visor mounting arrangement for a helmet in which the visor is pivoted to the helmet body by two spaced pivot means, at least one of which permits movement of the visor in the closed position thereof away from the helmet body, such movement effecting release of a latch device to permit pivoting of the visor to an open position.

The visor pivot means advantageously provide frictional restraint against at least the pivoting movement so that the visor is held in any desired intermediate position between the open and closed positions.

Preferably, the forward movement brings the visor to a position relative to a latch or guide pin fixed on the helmet such that the pin, which previously engaged the visor to prevent pivoting thereof, can enter an arcuate slot in the visor as this pivots upwardly to the open position.

The visor, pivots and guide pin can readily be constructed so that the visor can be mounted with its operative side to the left or right of the helmet as desired. The visor can be shaped so as to have one or more portions arranged to be conveniently engaged by the user's fingers or can have a separate member for this purpose attached to it.


FIG. 1 is a partial front view of a visor for use in a first helmet embodying the invention, parts of a pivot and latch device carried by the helmet body being also shown;

FIG. 2 is a partial front view of the helmet body with the visor secured thereto;

FIG. 3 is a fragmentary cross-sectional view on the line III--III of FIG. 2;

FIG. 4 is a partial developed front view of a visor for use in a second helmet embodying the invention, with parts of a pivot and a latch device carried by the helmet body being also shown;

FIG. 5 is a front view of part of a helmet body of FIG. 4, showing part of the pivot device; and

FIG. 6 is a sectional view of the pivot device, with parts spaced away from each other, taken on the line VI--VI on FIG. 5.

In the drawing, the visors are thin flexible transparent sheet members of generally conventional shape for covering an eye aperture 6 in the body 5 of a motorcyclist's helmet, typically, but not necessarily, of the full face type.

The visor 1 of FIGS. 1 to 3 thus has an upper edge 2 following a shallow concave curve and a lower edge 4 which is deeply convex. Between these edges are rounded ends at least approximately centred on axes about which the visor can pivot in use on the helmet body 5 between closed and open positions respectively covering and exposing the eye aperture 6. The visor 1 is of course curved around the front of the helmet body in use. At the wearer's right hand side (not shown) the visor has a circular aperture centred on the associated axis but on the left hand side an aperture 9 has a similarly centred semicircular end portion 10 which extends towards the other side of the visor into a parallel sided portion 11. The portion 11 communicates with an axially aligned narrower portion 12 and an arcuate portion 14 centred on the axis extends downwardly from the join of the portions 11 and 12. The portion 14 is of substantially the same width as the portion 12 and these portions form part of a latch device.

At the left hand side, the visor 1 is located between an outer and an inner disc 25,26 of a pivot device. A pivot disc 27 between the discs 25,26 is received in the aperture portion 11. The discs 25,26 and 27 are secured to the helmet wall (shown flat although it will be somewhat curved in actuality) by a screw 28 extending into the wall through central apertures in the discs. A latch or guide pin 30 is anchored in the helmet wall and extends outwardly through aligned apertures in the discs 25,26 and through the aperture 9, to co-operate with the portions 12,14 to form the latch device.

The pivot and latch devices are thus combined but could be spaced apart and independent.

At the right hand side, a generally similar pivot device, without the pin 30, comprises fixed outer and inner discs, a pivot disc and a screw, the pivot disc being received in the circular aperture of the visor. The inner and outer discs at each side frictionally engage the visor 1 so that it tends to remain at any intermediate position between the closed and open positions to which it is moved.

In the closed position of the visor 1, the pin 30 and disc 27 occupy the positions shown in solid line in FIG. 1 at the extreme inner ends of the aperture portions 12 and 11 respectively. The pin 30 and aperture portion 12 then act as a latch device to latch the visor against opening movement to expose the eye aperture 6.

To open the visor 1, its left hand end is manually pushed forward against the frictional engagement with the discs 25,26. A tag portion 31 of the visor, which could be provided at 31' and 31" instead or as well, facilitates this translational movement. When this movement ends, the visor 1 is in an intermediate closed position with the pivot disc 27 at the end portion 10 of the aperture 9, as shown in broken line and indicated by reference numeral 27' in FIG. 1. The guide pin 30 is now at the join of the aperture portions 11 and 12, as shown in broken line and indicated by reference numeral 30', and its axis is on the center line of the arcuate aperture portion 14.

There is of course no corresponding movement at the other side of the visor 1 which becomes slightly spaced away from the body 5 between the pivot devices by being slightly outwardly flexed. The visor 1 is thus cleared from the engagement with the body 5 around the eye aperture 6 and can be pivoted upwardly. The pivotal movement is limited by engagement of the pin 30 by the lower end of the aperture portion 14, the pin then having the position relative to the visor indicated in broken line and by reference numeral 30".

It will be noted that the entire movement can be effected from the left hand side of the visor.

Return movement of the visor 1 to the closed position is effected by pivoting the visor to bring the pin 30 out of the aperture portion 14 and then by movement of the visor back against the helmet. As soon as the pin 30 enters the aperture portion 12 the visor is latched into its closed position. The return movements can be carried out without use being made of the tag 31 if preferred, as the visor can be manually tilted down by engagement by the hand for example at a position along the upper edge 2 and brushed back to effect latching by engagement of its outer surface adjacent the left hand end. The return translational movement may also tend to take place as a consequence of wind pressure if the wearer drives at a sufficient speed, depending on the frictional resistance to such movement imposed by the discs 2,26.

In the helmet of FIGS. 4 to 6, the visor 100 has at the lefthand side an aperture 109 with a parallel sided portion 111 corresponding to the portion 11 of the visor 1, and a narrower parallel sided portion 112 extending parallel to the portion 111 and joined with it by an intermediate arcuate portion 114.

The associated pivot device comprises a lower disc 126 and with a central boss 127 protruding outwardly into the aperture 111. An outer disc 125 is assembled on the outer surface of the visor 100 and engages it by way of a peripheral rim 125'. A latch or guide pin 130 protrudes from the periphery of the disc 125 through the aperture 109, a peripheral recess 104 in the disc 126, and into a hole 105 in the helmet body 5. The discs 125,126 are secured to the helmet body 5 by a screw 128, and held against rotation by the screw and the pin 130. The pin 130 could instead be carried by the disc 126. The pin need not extend into a hole in the helmet body, the disc 126 being then secured to the helmet body by other means.

The boss 127 and the pin 130 function in relation to the aperture 109 in the same way as the pivot pin disc 27 and the pin 30 function in relation to the aperture 9 of the visor 1. Thus, from the normal closed positions of the boss 127 and pin 130 relative to the visor, these move to the locations shown by reference numerals 127' and 130' with the translational outward movement of the visor, and the pin moves to the location 130" with the upward pivotal movement to the open position.

At the righthand side of the visor 100, a like pivot device is provided, the boss 127 of which is received in a circular aperture 107 in the visor, and the guide pin 130 of which is received in an arcuate visor aperture 106 centered on the aperture 107. The aperture 106 shares with the aperture portion 114 the function of limiting pivotal movement of the visor on the helmet body.

Although it is preferred to arrange for operation of the visor from the left hand side of the helmet, because the wearer may be retaining hold of a motorcycle throttle with his right hand while moving the visor, it will be evident that operation from the right hand side can readily be provided for. With the helmet of FIGS. 1 to 3, if provision is made for reception of the guide pin 30 at either side of the helmet, the arrangements described can be readily changed from operation at one side to operation at the other, the visor being sufficiently flexible to be reversible.

The helmet of FIGS. 4 to 6 facilitates such a change because the pivot devices are alike and only reversal of the visor is required. A pin and co-operating aperture corresponding to aperture 106 in the visor 100 could be employed in the helmet of FIGS. 1 to 3 if desired.

Although the use of similar pivot elements at the two sides of the visor is convenient, it will be understood that different pivot means can be employed at the two sides, particularly when the facility of selecting the side from which operation takes place is not to be provided. The mounting at the other side can thus be a simple bearing or pivot pin, and can then make no substantial contribution to the frictional restraint of the visor movement.

Where visor reversal is not contemplated, one or more tags such as the tag 31 can be made to extend outwardly away from the adjacent surface of the visor, and/or a separate element, for example a rivet can be secured to extend outwardly from the visor as shown at 132 on FIG. 4. Reversability can however be retained if such an element is secured in a hole in the visor in such a way that it can be readily arranged to extend outwardly to one side or the other, as desired.
